This invention relates to a means for mounting a telescope sight upon a rifle and has for its principal object the provision of a mounting mechanism which will withstand the rifle recoil and maintain the telescgple1 permanently rigid.

other object of the invention is to provide a mounting which will eliminate the shearing of the mounting screws by the shock of the recoil, a disadvantage encountered with the present type of screw mount- IA further object of the invention is to provide a mounting'which may be used in connection with the regular rear sight mounting.

A still further object is to so construct the mounting that the telescope can be quickly and easily removed in the field and replaced by the regular rear peep slght.

Other objects and advantages reside 1n the detail construction of the invention, which is designed for simplicity, economy, and efliciency. These will become more apparent from the following description.

In the-following detailed description of the invention reference is had to the accompanyin drawings which forms a part hereof. Li e numerals refer to like parts in the description.

In the drawings:

Fig. 1 is a perspective view illustrating a telescope mounted on a rifle by the use of my improved mounting means.

Fig. 2 is a longitudinal section through the forwardmounting member.

Fig. 3 is a detail perspective view of the forward mounting block.

Fig. 4 is 'a' similar view of the forward telescope clamping ring.

Fig. 5 is a detail cross section through the rear telescope clamping ring and suport. p Fig. 6 is a perspective view of the rear telescope clamping ring support, with a peep sight sleeve in position in place of the rear clamping ring.

In the drawings, a rifle is designated in its entirety by the numeral 10 and a tele- 14.- so that, as the gun recoils, the breech all views of the drawing and throughout,

scope sight by the numeral 9. The rifle is provided with a rear sight clamp block 11, which supports the usual L-shaped rear sight support 12.

I mount the telescope by securing a mounting block 13 upon the breech block, which is illustrated at 14. The block 13 is secured in place by means of countersunk screws whichpass through openings 15 in the block 13 and are threaded into the co breech block 1 1. These screws, however, simply act to maintain the block 13 against the block 14. They are not subjected to shearing action by the recoil shock of the gun as is usual in screw mountings.

I provide for the recoil shock by forming a concave face on the bottom of the block 13 which fits over the convex upper surface of the breech block 14.. This concavity does not extend entirely to the rear edge of the 7G block .13 but terminates so as to leave'a downwardly projecting shoulder 16 at the rear of the block. This shoulder fits down over the rearward edge of the breech block block will act against this shoulder and so as to pull the mounting block 13 rearwardly without subjecting the mounting screws to any strain or shearing action.

In the top of the block 13, I form a conical depression 17 which extends through the two sides of the block to form concentrically arranged dovetailed grooves 32. At the axis of the depression 17 a pivot hole 18 is formed into or through the block 13.

The telescope 9 is clamped adjacent its forward extremity in a forward clamping ring 19, which is split as shown at 20 so that it may be passed over the telescope. The split 20 extends through a base 30 where it is clamped by means of clamping screws 21. Tightening the clamping screws 21 causes the clamping ring to firmly engage the telescope. In the base 30 of the clamping ring 19 annular undercut or dovetailed grooves 31 are concentrically formed about a projecting pivot pin 33.

In attaching the telescope, it is placed transversely of the rifle so that the base 30 of the clamping ring-19 will drop within the 100 depression 17, when the pivot pin 33 is in place in the hole 18. The telescope may be rotated about the pivot pin so as to bring it into alignment with the rifle. As it is rotated, the dovetails 31 will enter the dovetails 32 of the depression 17 so as to firmly lock the two members together.

The rearward extremity of the telescope 9 is mounted in a rear clamping ring 22 which is provided with a base 23, which is split as shown at 24. The base 23 carries a dovetail tenon 25 at each side which are narrowed to fit within the usual sight groove 26 of the rear sight support 12. The usual rear sight support is provided with two clamping screws 27, by means of which, the lateral position of the sight may be adjusted. The dovetail tenons 25 pass between these screws and, when the screws are tigh ened, the two tenons will be pressed together so as to close the split 24; and firmly clampthe locking rin 22 about the telescope.

To remove the telescope it is only necessary to loosen the lefthand clamping screw 27 so as to release the left hand tenon 25. The rear extremity of the telescope may then be swung to the right causing the rear clamping ring to rotate about the telescope as illustrated in the broken line in Fig. 5 until its tenons 25 are released from the sight support 12. The telescope may then be rotated to a lateral position so as to release the base of the forward clamping ring 1 9 from the block 18. The telescope may then be easily lifted from place.

It will be noted that one side of the base 23 of the rear clamping ring is rounded as shown at 28, so as to allow it to rock out of the sight slot 26 as the telescope is rotated.

After the telescope has been removed, any of the usual peep sight mountings 29 can be placed in the slot 26 and the screws 27 tightened to lock it in place. The rifle can then be used in the ordinary manner without the telescope. I

It is desired to call attention to the fact the rear extremity of the telescope is clamped in its ring and the ring is locked to the rifle by the use of the same clamping screw so that separate screws are unnecessary.

While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.

Having thus described the invention, what I claim and desire secured by Letters Patent is 1. Means for supporting .a telescope upon a rifle having a laterally extending rear sight support provided with clamping screws comprising: a pivoted telescope support secured to said rifle adjacent the forward extremity of said telescope; a split clamping ring adapted to surround said telescope rearwardly of said support; and a base on said clamping ring arranged to extend within a groove in said rear sight support, and be clamped in'place by said clamping screws.

2. Means for supporting a telescope upon a rifle having a laterally extending rear sight support provided with clamping screws comprising: a pivoted telescope sup port secured to said rifle adjacent the forward extremity of said telescope; a split clamping ring adapted to surround said telescope rearwardly of said support; a base on said clamping ring arranged to extend within a groove in said rear sight support, and be clamped in place by said clamping screws; and a rounded surface on'one side of said base adapted to allow the base to rotate out of said groove when said telescope is rotated about its pivot.

3. A telescope mount for a rifle comprising: a mounting block secured to said rifle and provided with an elongated depression in its upper face having concentric arcuate ends and opening thru the sides of said block, the forward and rear walls of said depression being undercut; a mount member for supporting a telescope; a base on said member, said base having a projection shaped to fit said elongated depression, the arcuate ends thereof being formed to fit the undercut ends of' said depression whenaligned therewith, whereby the member can be released by turning said ends out of engagement; and means on said block at the common center of curvature of its ends for guiding said projection, when rotated, to move about the center of said depression.

4.
